So red meat and whole fat dairy reduce the risk of a heart attack, stroke or early death now apparently. Oh how the press love to overegg a diet and health story!
Here we go again, the headlines are full of it today, with media outlets claiming Fat lot of good – Cheese and red meat ARE good for you – slashing your risk of dying young, Steak and cheese are back on the menu!, Red meat and cheese back on menu in healthy diet for heart, and Grill up that steak and roll out a wheel of cheddar – because red meat and cheese are back on the menu for healthy living.
The headlines are based on research presented at the European Society of Cardiology conference in Munich. Dr. Andrew Mente and colleagues from McMaster University, Ontario in Canada used five large international studies to develop a dietary scoring system that measured the health benefits of different foods.
Results suggest that unprocessed red meat, fish and whole fat dairy reduce risk of early death, heart disease and stroke.
The seven food groups included were vegetables, fruit, pulses (peas, beans and lentils), nuts, fish, dairy and unprocessed red meat. Each food group was assigned a score of one (lowest intake) up to five (highest intake). So the lowest score would be seven and the highest, 35.
Those with a very low score tended to eat fruit, vegetables, a small amount of nuts or pulses and very little dairy, meat and/or fish. This included poor quality diets where 70-80 percent of the energy came from carbohydrates.
Those with higher scores, eating the most dairy and red meat, saw their chances of early death fall by 25 percent and fatal heart attack decrease by 22 percent. People who had three portions of dairy and 120 grams of unprocessed red meat per day benefited the most.
Diets containing lots of fruit, vegetables, nuts, pulses, dairy, red meat and fish may offer some advantage compared to a sub-optimal diet based on white rice – but that doesn’t make it an optimal diet. That’s like saying a Big Mac (with cheese and salad) is healthier than a chip buttie!
Results also showed that fruit, vegetables, nuts and pulses are an essential part of a healthy diet, but that doesn’t make such good headlines so all we are hearing about is how you should be chowing down on steak and ice-cream for a healthy heart.
Previous research from this group showed similar results but the methodology, interpretation and conclusions have been questioned.
Firstly, the quality of carbohydrate was not assessed. The World Health Organisation recommends an optimum diet of at least 55 per cent of total energy from a variety of carbohydrate sources for all ages except for children under the age of two.
The key point here is a variety of carbohydrate sources - in some low-income countries, the diet may be dominated with processed white rice - lacking in fibre, vitamins and minerals compared to wholegrain foods.
President of the Physicians Committee (PCRM), Dr. Neal Barnard, and colleagues said the main conclusion of the previous study was: "It is better to be rich and healthy than poor and sick."
People in low-income countries getting 75-80 per cent of their calories from carbohydrates (mainly white rice) are more likely to die earlier than those with a more mixed diet (with less than 50 per cent coming from carbs).
No kidding Sherlock!
Barnard et al. say that the increased risk of death linked to carbohydrates probably reflects factors associated with poverty (inadequate food availability, poorly ventilated stoves, pollution and limited health-care access).
They also point out how the same study showed that eating carbohydrate-rich fruits, vegetables and pulses were linked to lower risk of death, further suggesting that refined carbohydrate (white rice) consumption is a proxy for poverty.
They say: "The authors call for reconsideration of global dietary guidelines, and we fully agree. It is time to tell the truth: the key to improving health is not decreasing carbohydrate consumption, but escaping poverty, gaining access to medical care, and eating fruits, vegetables, and legumes. These factors decrease both cardiovascular and non-cardiovascular total mortality."
More research is needed to see how a plant-based diet containing plenty of fruit, vegetables, wholegrains, pulses, nuts and seeds compares to the model used in this study. Until then, there is not enough evidence to justify calling for a change to current guidelines that recommend reducing your intake of red meat and saturated fat.
This study supports recommendations on the consumption of fruits, vegetables and pulses but provides no basis for a change in global dietary recommendations.
Dr Kim Allan Williams, of the American College of Cardiology, says: "The real value with this study is to get everyone to recognize that there is a direct correlation between food intake - quantity, quality and substance - and CV [cardiovascular] events and death. If we can just get everyone to recognize that, that could change the world."
